“…Furthermore, Hickley, Muchiri, Britton, and Boar (2008) reported that highly abundant common carp with anthropogenic disturbance of the littoral vegetation, particularly through clearance and burning could have reduced spawning areas of Nile tilapia and resulted in its disappearance in Lake Naivasha. The major reasons put forth by different ecologists for the predominance of common carp over the more prized endemic fish fauna in lakes were food competition due to more or less identical food spectra, higher fecundity, spawning facilities prevailing in the lake, shorter incubation period, better fertilisation and better growth rate (Naik, Rashid, Balkhi, & Bhat, 2015). Among these, the diet similarity observed in Lake Ziway could be one of the causes of the decline of Nile tilapia.…”

Diet overlap of non‐native common carp and native Nile tilapia: A potential cause for population reduction of Nile tilapia stock in Lake Ziway, Ethiopia

Lake Ziway harbours indigenous and exotic fish species including Nile tilapia (Oreochromis niloticus) and common carp (Cyprinus carpio). Nile tilapia was the dominant and preferred fish. However, its contribution to total catch has dramatically declined from 89.3% in 1994 to 27% in 2014 while the introduced common carp has increased from 0% before 2012 to 25% in 2014. Common carp potentially compete with Nile tilapia for available resources and could be a cause for the decline. Thus, the study explored the dietary overlap of the two species from April to August 2017. Schoener's overlap index (α) revealed significant dietary overlap between the two species (α = 0.84, between juveniles and α = 0.63, between adults). Juveniles fed mainly on animal origin (zooplankton and insects), while adult Nile tilapia have consumed plant origin (macrophyte and phytoplankton), and adult common carp fed on macrophytes and detritus. The presence of significant dietary overlap between the two species, particularly due to intense competition among juveniles, might cause the reduction of Nile tilapia stock because the native species has shown a competitive disadvantage for food in the presence of common carp. This study provides baseline information to researchers and decision makers working towards the sustainable resource utilisation of the system.

“…This species has a high market price in the commercial market (Sultana et al, 2018), is locally available, is cultivable in small ponds, matures in 1 year, is easier for artificial breeding, has a prolonged breeding period, is delicious to eat, and is environmentally friendly. Numerous explorations on the biology of this species are available, such as on feeding (Naik et al, 2015, Lashari et al, 2010, life-history character (Hossain et al, 2013), and induced spawning (Sarkar et al, 2004). Lashari et al (2007) sampled the gonado-somatic index (GSI) and reproductive success of C. reba in fishponds in the area of Jacobabad, Sindh, Pakistan.…”

An experiment on brood rearing and induced breeding of the near threatened fish species Raikor, Cirrhinus reba using the pituitary gland (PG), was conducted from March to August 2020 at the Floodplain Sub-station of Bangladesh Fisheries Research Institute, Santahar, Bogura. Broods were collected and reared in the ponds of the hatchery complex. The total length (cm), body weight (g), gonad weight (g), and gonado-somatic index (%) of this species were measured during the rearing period. To standardize the breeding technique, a total of 90 brood fish of C. reba were treated with different doses of PG, specifically, 2.0, 4.0, 6.0 mg/kg body weight for females and 1.0, 2.0, 3.0 mg/ kg body weight for males in different treatments, namely T 1 , T 2 , and T 3 respectively. A significant difference (p<0.05) was observed in fecundity, ovulation (%), and the fertilization rate (%) among the treatments. Based on the results, T 2 (4.0 mg/kg body weight for females, 2.0 mg/kg body weight for males) produced the most favorable results. The current observations could be applied to C. reba stimulated breeding for the advancement of hatchery formation. More research on the nursing, nurturing, and culture of the near-threatened C. reba at varied densities and feedings is necessary for their conservation and restoration.

The gonadosomatic index (GSI) and fecundity of the threatened Cirrhinus reba (Hamilton) was studied over a period of one year from January to December 2015 in the Ganges River (northwest Bangladesh). The GSI index indicated that the C. reba breeding season in the Ganges was from June to September with the peak in August. Fish fecundity increased with increasing fish length and weight, and the highest fecundity (265,042.23) was recorded in a fish with a total length, a body weight, and an ovary weight of 23.80 cm, 136.00 g and 45.00 g, respectively. There was a linear relationship between fecundity and total length (r = 0.871), body weight (r = 0.872), and ovary weight (r = 0.879), with that between ovary weight and fecundity being the strongest.
